HARROW ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 496,036, dated April25, 1893.

Application filed August 4, 1892. Serial No. 442,181. (No model.)

To all whom it may concern.-

Be it known that we, CHARLEs ALBERT AN- DERSON and JOHN SMALLWooDWINSTON, citizens of the United States, residing at Sturgis, in thecounty of Union and State of Kentucky, have invented. a new and usefulHarrow Attachment, of which the following is a specification.

Our invention relates to improvements in [O attachments for barrows, andthe object in view is to provide an attachment designed for use uponhard soil and where a disk-harrow would be impracticable.

With this and various other objects in I 5 view, the invention consistsin certain features of construction hereinafter specified andparticularly pointed out in the claims.

Referring to the drawings:-Figure 1 is a perspective view of a harrowprovided with attachmentsin accordance with ourinvention.

Fig. 2 is a detail in perspective of the attachment. Fig. 3 is atransverse section through the same.

Like numerals of reference indicate like 2 5 parts in all the figures ofthe drawings.

1 designates a series of transverse harrowbars, having teeth 2,depending therefrom. These harrow bars are connected loosely byintermediate links 3, which engage with eyes 0 4, formed at the oppositesides of pairs of clips 5, with which each of the bars is provided nearits ends.

6 designates the bar of the attachment, and

the same is designed to be located either in front or in rear of theharrow, but preferably in front Where the large clods may be cutprevious to operation thereon by the teeth of the harrow. This bar 6 ispreferably rectangular in cross-section, and is provided at oppositesides of its center with eyes 7, to be loosely connected by links to thefront bar of the harrow. At opposite sides of the center the bar is alsoprovided with transverse openings 9, and

through each opening passes a transverse eye- 5 bolt 10, the eyes 11 ofsaid bolts being located in front of the transverse beam 10 and havingtheir upper edges serrated or toothed as at 12.

Arms 13, are secured rigidly to the rear ends of the eye-bolts, therebeing preferably, and

in this instance, a pair at each side of the center of the transversebeam 6. These arms 13 are provided at their inner ends withforwardly-disposed pins 14, which takeinto bearing recesses 15 formedupon the under sides of a pair of connecting-rods 16. The connectingrods 16 have their inner ends pivoted at 17 to the opposite extremitiesof a centrally pivoted rocking-lever 18, which is mounted upon the rearside of an I-shaped standard 19. The standard 19 isbolted upon the upperside of the beam 6 at about the center thereof, and is provided at itsfront side with an eye 20. Upon a bearing-block 21, mounted upon thebeam 6 at one side of the center is pivoted a hand-lever 22, and thesame is loosely connected by a bolt 23, with one of the connecting-bars16. A sleeve 24 with depending locking teeth 25, is mounted upon thelever 22 and is designed to engage with the notches 26, formed in acurved locking-bar 27 rising from the standard 21. A bell-crankedlocking lever 28 is pivoted on the-hand lever, is spring pressed by aspring 29, and is loosely connected to the rear sleeve by means of alink 30. It will thus be seen that by a vibration of the hand-lever theconnecting-bars may be moved in or out and thus the eye-bolts bepartially rotated in either direction. By reason of the connecting barsbeing pivoted to the sides of the center of the small lever 18 the boltsat opposite sides of the center are given opposite movements.

31 designates a series of curved cutters or teeth, whose convexed edgesare beveled to form cutting edges and the same are secured 8 5 at theirupper ends to reduced cylindrical shanks 32. Each shank passes throughan eye 11 and-above the same is threaded and receives a nut 33 and anintermediate looking washer 34, Whose under side is serrated or toothedat 35, so as to engage with the serrations or teeth formed upon theupper sides of the eyes 11. By a proper manipulation of the nuts andserrated Washers the shanks may be secured in proper relative positionand ab- 5 solutely locked against any movement within the eyes.

36 and 37 designate a pair of overlapping adjusting bar-sections theouter ends of which have eyes and are connected by links 38 with the eye19 of the attachment bar and with the corresponding eye located at thecenter of the rear transverse harrow bar. Each of the bar sections 36and 37 is provided with keepers 39 whereby the bar section s are looselyor slidably connected. A curved locking standard 40 rises from the barsection 36 and a fulcrum block 41 depends from the under side of saidbar-section opposite the locking standard. A bearing block 42 rises fromthe section 37 within the standard and the latter is embraced by abifurcated lever 43 which is pivoted by bolts 44 to the bearing blocksof the two bar-sections. A locking-sleeve 45, is mounted forreciprocation on the lever and the same has a tooth 46, designed toengage and lock with the notches in the aforesaid locking-bar. Abell-cranked locking-lever 48, is pivoted to the lever, a spring 49being interposed between the upper branch of the same and the lever,while a link 50. loosely connects the lower branch of the bell-crankedlever with the locking-sleeve.

It will be understood that our attachment may be employed in connectionwith any style of harrow, and we have merely illustrated the same inconnection with the present form of harrow for the purpose of showingits applicability. We therefore do not limit our invention to use inconnection with any particular form of harrow.

From the foregoing description in connection with the accompanyingdrawings it will be seen that we have provided a cheap and simpleattachment that may be used either at the front or rear of a harrow andwhich will operate in a manner similar to the well-known disk harrowwhich is designed to operate upon hard soil and thus prepare the same tobe operated upon by the teeth of the usual harrow following thereafter.

By our invention we secure the same results as the disk harrow and yetaccomplish it merely by the attachment that may be cheaply manufacturedand applied to any ordinaryharrow in use.

Having described our invention, what we claim is- 1. Theherein-described attachment for harrows, the same consisting of atransverse beam, a series of transverse eye-bolts, cutters mounted inthe eye-bolts in front of the beam, crank arms mounted on the rear endsof the eye-bolts and adapted to oscillate, connecting bars looselyconnected to the pins of the crank arms, and a lever for operating theconnecting bars, substantially as specified.

2. The herein-described attachment for harrows, the same consisting of atransverse beam provided with a series of transverse openings, eye-boltsmounted to oscillate in the openings, the eyes of the bolts beingprovided upon their upper sides with serrations, curved cutters havingtheir shanks passed through the eyes and threaded at their upper ends,nuts mounted on the threaded ends of the shanks of the cutters, washershaving their under sides serrated and interposed between the nuts andthe upper ends of the eyes and means for oscillating the bolts,substantially as specified.

3. The herein-describedattachmentforharrows, the same consisting of atransverse bar provided at opposite sides of its center with transverseopenings, eye-bolts terminating at their rear ends in cranks mounted forrocking in the openings, cutters having shanks mounted and secured inthe eye-bolts, a standard rising from the center of the bar or beam, anoscillating lever pivoted on the standard, opposite connecting barsloosely connected to the crank pins and to the opposite extremities ofthe oscillating lever, a hand lever fulcrumed on the beam and connectedto one of the bars, and means for locking the hand lever, substantiallyas specified.

4. The combination with a series of transverse harrow bars looselyconnected together and provided with depending teeth, and the rear barprovided upon its upper side with a central standard having an eye, of atransverse beam provided upon its upper side with a bearing standardalso having an eye,

said beam being loosely connected to one of the end harrow bars, aseries of oscillating eye-bolts journaled in openings formed in thebeam, curved cutters removably mounted in the eyes of the bolts, meansfor oscillating the bolts, and an adjusting bar mounted upon thestandards of the beam and barrow bar, links connecting the same with theeyes of said beam and harrow bar, and means for locking the eye boltsand adjusting the adjusting beam, substantially as specified.

In testimony that we claim the foregoing as our own we have heretoafiixed our signatures in the presence of two witnesses.
